Description

Technical Field

[0001] This utility model relates to the technical field of furnace temperature testers, and in particular to a magnetic furnace temperature tester. Background Technology

[0002] In industrial production, temperature is a critical process parameter. In surface mount technology (SMT) manufacturing in the electronics industry, precise furnace temperature control is essential to ensure the soldering quality between electronic components and circuit boards. Excessive furnace temperature can lead to solder splatter and component damage, while insufficient temperature results in weak solder joints, incomplete soldering, and other defects, affecting the performance and reliability of electronic products. In automotive painting processes, oven temperature control directly impacts paint adhesion, gloss, and durability. A suitable oven temperature ensures uniform paint drying, forming a high-quality coating and enhancing the vehicle's appearance and corrosion resistance. In metal heat treatment, accurate furnace temperature control is crucial for achieving the desired structure and performance of metal materials. Different metal materials and heat treatment processes have very strict requirements for furnace temperature; even slight temperature deviations can lead to significant changes in material properties, affecting the strength, toughness, and wear resistance of components. Furnace temperature testing instruments, using high-precision temperature sensors and advanced signal processing technology, can accurately measure the temperature at different locations and times within the furnace.

[0003] With the continuous development of technology, magnetic furnace temperature testers have emerged. They utilize magnetic technology for quick installation and can be easily attached to furnace bodies and the surfaces of objects being tested of various shapes and materials. Combined with high-precision temperature sensors and advanced signal processing technology, they enable accurate measurement and real-time monitoring of furnace temperature, which helps improve product quality, reduce production costs, and enhance the automation and reliability of the production process. However, the test head is exposed to the outside for a long time, and the wear on the probe surface will gradually increase. The wear on the surface will change the characteristics of the test head, thus affecting the accurate perception and measurement of temperature. Utility Model Content
